Legal Definitions - Office of Surface Mining Reclamation and Enforcement

The Office of Surface Mining Reclamation and Enforcement (OSM) is a department within the U.S. Department of the Interior. Its main responsibility is to protect against the negative effects of surface coal mining by enforcing laws related to surface mining and restoration. OSM also assists states and local governments, which have primary responsibility in this area.

For example, if a coal mining company is not following the laws related to surface mining and restoration, OSM can take action to enforce those laws and ensure that the company is held accountable. OSM can also provide guidance and support to states and local governments to help them better manage surface mining activities and protect the environment.
